SammaPix vs ShortPixel
ShortPixel is a well-known image compression service — but it sends your files to a server and runs on a credit system. SammaPix is completely free, processes everything in your browser, and adds AI-powered renaming.
Choose SammaPix if you…
- Want 100% free compression with no credit limits
- Care about privacy (files never leave your device)
- Need AI-generated SEO filenames and alt text
- Don't want to create an account just to compress
Choose ShortPixel if you…
- Use WordPress and need a plugin that auto-optimizes
- Need AVIF compression output
- Want CDN-delivered, automatically compressed images

The key differences
Privacy — ShortPixel uploads your images to its servers
ShortPixel's compression engine runs on their servers, which means every image you process is transmitted over the internet. SammaPix compresses and converts entirely in your browser using WebAssembly and the Canvas API. Your files stay on your device at all times — critical if you handle client photos, legal documents, or private images.
Credits vs. truly free — a real difference for casual users
ShortPixel's free tier gives you 100 credits per month — each compressed image uses one credit. If you exceed the limit you need to buy more. SammaPix's compression is unlimited and free forever, no credit system, no account required. You can compress 500 images in a day and pay nothing.
AI rename — a feature ShortPixel doesn't offer
SammaPix uses Google Gemini to analyze each image and generate an SEO-friendly filename and alt text description. Upload IMG_7732.jpg, get back fresh-basil-pasta-recipe-close-up.webp. ShortPixel focuses purely on compression and delivery — it has no AI rename feature at any price point.
Where ShortPixel wins — WordPress and automation
ShortPixel's WordPress plugin is its strongest selling point. It automatically compresses every image you upload to WordPress, with no manual steps. If your entire workflow lives inside WordPress, ShortPixel is a natural fit. SammaPix is a browser-based tool designed for manual batch workflows — it has no WordPress plugin.
Who should switch from ShortPixel to SammaPix?
ShortPixel is a reliable paid service with a strong WordPress focus. Consider SammaPix if:
- You're hitting ShortPixel's monthly credit limits. SammaPix compression has no limits — process as many files as you need, for free.
- You work with sensitive images. Legal, medical, or client photos should not be uploaded to third-party servers. SammaPix is 100% client-side.
- You want SEO-optimized filenames automatically. ShortPixel compresses your images but keeps the original filenames. SammaPix can rename them with AI in the same workflow.
- You don't use WordPress. For standalone websites, static sites, or manual workflows, a browser tool like SammaPix is faster and simpler.
